'(GRENTED UNDER THE PROVISIONS OFTHE ACT OF MARCH 3, 1921, 41 STAT. L, 1313.)

T0 all whom it may concern:

. is a specification.

This invention relates to combing machines of the type in which the lap is mounted vertically above the machine, as in double combing machines inwhich the combed material is delivered on both sides of the machine, such as illustrated in British patent 4647 of 1911. l.

In single combing machines as usually constructed there is no difliculty regarding the lap when the latter runs out, "for it is placed toward the back of the machine and is drawn forward, almost horizontally, over the usual guide.v In double combing machines, however, the laps have to be placed some distance above and in front of the combing mechanism so there is the drawback that when a lap runs out its last portionsince it has nothing to support it after it leaves the 'creelis liable to fall down on to the feed roller with the result that the machine is choked and stopped, and a concombing machines of the above stated type a run-out lap can, without the drawbacks mentioned, be combed entirely to the end.

According to this invention, between the creel and the feed roller, I provide a lap guide comprising a number of horizontal members around and betweenwhich the lap may be drawn, the said members being so arranged as successively to support the rear portion of a run-out lap as it is drawn forward to and by the feed roller; the rear portion of'the lap rests or falls upon and partially around one after the other of the said members; and the lap guide may also comprise a pair of vertical side plates connected by the horizontal supporting members each of the latter being, when the guide is in posltion on the machine, more distant from the feed roller than from the member and 3 are longitudinal sectional views illustrating the invention with the lap occupying progressive positions.

In the said drawings A is one of two similar side plates, B B B are supporting members extending from one to the other of the side plates, and C is a plate adapted to guide the lap to the feed roller. The upper end of the guide is removably secured to the creel by means of a pair of links D pivoted upon the rear creel rod E and each provided with a slot D by which it engages with opposite ends of a rod F extending across the guide; the lower end of the guide is provided with foot pieces G which are notched or grooved as at G to engage with and rest upon the nipper. The position of the feed roller is indicated at J.

L indicates the lap, and in the figures the approximate positions of the rear portion of a run-out lap are shown: in Figure 1 the lap is shown passing down and around the supports before the end of the lap has passed from the creel; in Figure 2 the lap is shown after the last portion has been drawn clear of the support B, the rearmost portion L having fallen down behind the support B, and owing to the comparatively short distance between the twosupports B B the end of the portion L does not reach the feed roller; and in Figure 3 the position of the lap is shown when the portion L has been drawn clear of the support B and has fallen down in front of the, support BF, and since the distance between the two supports B B is smaller than the distance'between the support, B and the feed roller, the end of L does not reach the said roller. After the rearmost portion of the lap has been drawn clear of the support B it is supported by the member B for a time, and is then drawn down on to the guide C which leads it to the feed roller; After leaving the sgpport B the end of the lap drops behind the back end of C, as is shown by broken lines in Figure 3. It will be noted that in the posi tions shown in Figures 2 and 3 the pendent end L of the lap is clear of the more forward portion thereof owing to the distance between and also to the relative positions of the guides and supports.

In the example shown a portion of the side plates A is cut away as at a to avoid a shaft of the machine for which it was designed. The details of construction may, however, be varied without departing from this invention: for example the support B may consist of two separate rods; or the supports 13 B may be made in the form of one bar, although the construction shown is preferable, for it permits the hand tobe inserted between B and B when placing a new lap in position.

Claims:

1. As an improvement in combing machines, a lap guide comprising spaced apart side plates, and a plurality of supporting members interposed between said plates and spaced apart longitudinally of the side plates to successively support the rearmost end of the lap in its travel.

2. As an improvement in combing machines, a lap guide comprising spaced apart members interposed between said plates and spaced apart longitudinally of the side plates 7 to successively support the rearmost end of the lap in its travel, and a guide plate for directing the lap to the usual feed roll.

3. As an improvement in combing machines a lap guide comprising-a series of horizontally disposed supporting members, and a guideplate, each supportingmember being nearer to the one above it than to said guide plate, to support the itearrnost end oi the lap inits travel.

In testimony whereof I have aflixed. my signature, in presence of two witnesses.
